eggys are easy to clean and hold more paintballs than halo or reloaders...sure its only 10-20 but that can make a difference.
a z board gives you a much more consistent feed of paintballs than the y board does. no problems with z boards what so ever.
halos and reloaders have problems here and there with people, some have huge problems, others never have a problem. guess it comes down to luck of the draw at the factory? hehe
